CONCRETE COMPOSITION, AND CONCRETE-KNEADED MATTER
PROBLEM TO BE SOLVED: To provide a concrete composition which can prevent heat generation due to curing of a concrete-kneaded matter having a comparatively small water-binder ratio and high-temperature history received by a concrete cured body from affecting expression of a strength of the concrete cured body.SOLUTION: A concrete composition contains cement as a binder, a coarse aggregate and a fine aggregate, and is used by kneaded with water so that a water binder ratio is 40% or less, where the coarse aggregate has a coefficient of thermal expansion of 8×10/°C or more, and a coefficient of thermal expansion of a mortar component other than the coarse aggregate is 8×10/°C or more and 15×10/°C or less.SELECTED DRAWING: None
【課題】水結合材比が比較的少ないコンクリート混練物の硬化に伴う発熱やコンクリート硬化体が受ける高温履歴がコンクリート硬化体の強度の発現に影響するのを抑制することができるコンクリート組成物を提供することを課題とする。【解決手段】結合材としてのセメントと、粗骨材と、細骨材とを含み、水結合材比が４０％以下となるように水と混練されて使用されるコンクリート組成物であって、前記粗骨材は、熱膨張係数が８×１０−６／℃以上であり、粗骨材以外のモルタル成分の熱膨張係数が８×１０−６／℃以上１５×１０−６／℃以下である。【選択図】なし
